This is how the barrel works: the inside of the rifled barrel (the bore) consists of many fine cuts that extend for the full length of the barrel. These cuts look like 10 sets of tiny train tracks. The track portion is called the “land.” The portion that is cut away is called the “groove.” The purpose of the land and groove pattern is to “glide and guide” the paintball down the bore, as well as provide a “spin-free projection” to stabilize the paintball in flight.

The RAP4 rifled barrel kit will not just make your marker look and feel better, but will also enhance your accuracy as well!
